Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

We are excited to participate and present Syscoin Platform's ideal characteristics and capabilities towards a well-rounded Reddit Community Points solution!
Our scaling solution for Reddit Community Points involves 2-way peg interoperability with Ethereum. This will provide a scalable token layer built specifically for speed and high volumes of simple value transfers at a very low cost, while providing sovereign ownership and onchain finality.
Token transfers scale by taking advantage of a globally sorting mempool that provides for probabilistically secure assumptions of “as good as settled”. The opportunity here for token receivers is to have an app-layer interactivity on the speed/security tradeoff (99.9999% assurance within 10 seconds). We call this Z-DAG, and it achieves high-throughput across a mesh network topology presently composed of about 2,000 geographically dispersed full-nodes. Similar to Bitcoin, however, these nodes are incentivized to run full-nodes for the benefit of network security, through a bonded validator scheme. These nodes do not participate in the consensus of transactions or block validation any differently than other nodes and therefore do not degrade the security model of Bitcoin’s validate first then trust, across every node. Each token transfer settles on-chain. The protocol follows Bitcoin core policies so it has adequate code coverage and protocol hardening to be qualified as production quality software. It shares a significant portion of Bitcoin’s own hashpower through merged-mining.
This platform as a whole can serve token microtransactions, larger settlements, and store-of-value in an ideal fashion, providing probabilistic scalability whilst remaining decentralized according to Bitcoin design. It is accessible to ERC-20 via a permissionless and trust-minimized bridge that works in both directions. The bridge and token platform are currently available on the Syscoin mainnet. This has been gaining recent attention for use by loyalty point programs and stablecoins such as Binance USD.

Solutions

Syscoin Foundation identified a few paths for Reddit to leverage this infrastructure, each with trade-offs. The first provides the most cost-savings and scaling benefits at some sacrifice of token autonomy. The second offers more preservation of autonomy with a more narrow scope of cost savings than the first option, but savings even so. The third introduces more complexity than the previous two yet provides the most overall benefits. We consider the third as most viable as it enables Reddit to benefit even while retaining existing smart contract functionality. We will focus on the third option, and include the first two for good measure.
  1. Distribution, burns and user-to-user transfers of Reddit Points are entirely carried out on the Syscoin network. This full-on approach to utilizing the Syscoin network provides the most scalability and transaction cost benefits of these scenarios. The tradeoff here is distribution and subscription handling likely migrating away from smart contracts into the application layer.
  2. The Reddit Community Points ecosystem can continue to use existing smart contracts as they are used today on the Ethereum mainchain. Users migrate a portion of their tokens to Syscoin, the scaling network, to gain much lower fees, scalability, and a proven base layer, without sacrificing sovereign ownership. They would use Syscoin for user-to-user transfers. Tips redeemable in ten seconds or less, a high-throughput relay network, and onchain settlement at a block target of 60 seconds.
  3. Integration between Matic Network and Syscoin Platform - similar to Syscoin’s current integration with Ethereum - will provide Reddit Community Points with EVM scalability (including the Memberships ERC777 operator) on the Matic side, and performant simple value transfers, robust decentralized security, and sovereign store-of-value on the Syscoin side. It’s “the best of both worlds”. The trade-off is more complex interoperability.

Syscoin + Matic Integration

Matic and Blockchain Foundry Inc, the public company formed by the founders of Syscoin, recently entered a partnership for joint research and business development initiatives. This is ideal for all parties as Matic Network and Syscoin Platform provide complementary utility. Syscoin offers characteristics for sovereign ownership and security based on Bitcoin’s time-tested model, and shares a significant portion of Bitcoin’s own hashpower. Syscoin’s focus is on secure and scalable simple value transfers, trust-minimized interoperability, and opt-in regulatory compliance for tokenized assets rather than scalability for smart contract execution. On the other hand, Matic Network can provide scalable EVM for smart contract execution. Reddit Community Points can benefit from both.
Syscoin + Matic integration is actively being explored by both teams, as it is helpful to Reddit, Ethereum, and the industry as a whole.

Proving Performance & Cost Savings

Our POC focuses on 100,000 on-chain settlements of token transfers on the Syscoin Core blockchain. Transfers and burns perform equally with Syscoin. For POCs related to smart contracts (subscriptions, etc), refer to the Matic Network proposal.
On-chain settlement of 100k transactions was accomplished within roughly twelve minutes, well-exceeding Reddit’s expectation of five days. This was performed using six full-nodes operating on compute-optimized AWS c4.2xlarge instances which were geographically distributed (Virginia, London, Sao Paulo Brazil, Oregon, Singapore, Germany). A higher quantity of settlements could be reached within the same time-frame with more broadcasting nodes involved, or using hosts with more resources for faster execution of the process.
Addresses used: 100,014

It is important to note that this POC is not focused on Z-DAG. The performance of Z-DAG has been benchmarked within realistic network conditions: Whiteblock’s audit is publicly available. Network latency tests showed an average TPS around 15k with burst capacity up to 61k. Zero-latency control group exhibited ~150k TPS. Mainnet testing of the Z-DAG network is achievable and will require further coordination and additional resources.
Even further optimizations are expected in the upcoming Syscoin Core release which will implement a UTXO model for our token layer bringing further efficiency as well as open the door to additional scaling technology currently under research by our team and academic partners. At present our token layer is account-based, similar to Ethereum. Opt-in compliance structures will also be introduced soon which will offer some positive performance characteristics as well. It makes the most sense to implement these optimizations before performing another benchmark for Z-DAG, especially on the mainnet considering the resources required to stress-test this network.

Cost Savings

Total cost for these 100k transactions: $0.63 USD
See the live fee comparison for savings estimation between transactions on Ethereum and Syscoin. Below is a snapshot at time of writing:
ETH price: $318.55 ETH gas price: 55.00 Gwei ($0.37)
Syscoin price: $0.11
Snapshot of live fee comparison chart
Z-DAG provides a more efficient fee-market. A typical Z-DAG transaction costs 0.0000582 SYS. Tokens can be safely redeemed/re-spent within seconds or allowed to settle on-chain beforehand. The costs should remain about this low for microtransactions.
Syscoin will achieve further reduction of fees and even greater scalability with offchain payment channels for assets, with Z-DAG as a resilience fallback. New payment channel technology is one of the topics under research by the Syscoin development team with our academic partners at TU Delft. In line with the calculation in the Lightning Networks white paper, payment channels using assets with Syscoin Core will bring theoretical capacity for each person on Earth (7.8 billion) to have five on-chain transactions per year, per person, without requiring anyone to enter a fee market (aka “wait for a block”). This exceeds the minimum LN expectation of two transactions per person, per year; one to exist on-chain and one to settle aggregated value.

Developer & User Diligence

Trade-off

The Syscoin Ethereum Bridge is secured by Agent nodes participating in a decentralized and incentivized model that involves roles of Superblock challengers and submitters. This model is open to participation. The benefits here are trust-minimization, permissionless-ness, and potentially less legal/regulatory red-tape than interop mechanisms that involve liquidity providers and/or trading mechanisms.
The trade-off is that due to the decentralized nature there are cross-chain settlement times of one hour to cross from Ethereum to Syscoin, and three hours to cross from Syscoin to Ethereum. We are exploring ways to reduce this time while maintaining decentralization via zkp. Even so, an “instant bridge” experience could be provided by means of a third-party liquidity mechanism. That option exists but is not required for bridge functionality today. Typically bridges are used with batch value, not with high frequencies of smaller values, and generally it is advantageous to keep some value on both chains for maximum availability of utility. Even so, the cross-chain settlement time is good to mention here.

Cost

Ethereum -> Syscoin: Matic or Ethereum transaction fee for bridge contract interaction, negligible Syscoin transaction fee for minting tokens
Syscoin -> Ethereum: Negligible Syscoin transaction fee for burning tokens, 0.01% transaction fee paid to Bridge Agent in the form of the ERC-20, Matic or Ethereum transaction fee for contract interaction.

Z-DAG

Zero-Confirmation Directed Acyclic Graph is an instant settlement protocol that is used as a complementary system to proof-of-work (PoW) in the confirmation of Syscoin service transactions. In essence, a Z-DAG is simply a directed acyclic graph (DAG) where validating nodes verify the sequential ordering of transactions that are received in their memory pools. Z-DAG is used by the validating nodes across the network to ensure that there is absolute consensus on the ordering of transactions and no balances are overflowed (no double-spends).

Benefits

  • Unique fee-market that is more efficient for microtransaction redemption and settlement
  • Uses decentralized means to enable tokens with value transfer scalability that is comparable or exceeds that of credit card networks
  • Provides high throughput and secure fulfillment even if blocks are full
  • Probabilistic and interactive
  • 99.9999% security assurance within 10 seconds
  • Can serve payment channels as a resilience fallback that is faster and lower-cost than falling-back directly to a blockchain
  • Each Z-DAG transaction also settles onchain through Syscoin Core at 60-second block target using SHA-256 Proof of Work consensus

Z-DAG White Paper
Useful read: An in-depth Z-DAG discussion between Syscoin Core developer Jag Sidhu and Brave Software Research Engineer Gonçalo Pestana

Trade-off

Z-DAG enables the ideal speed/security tradeoff to be determined per use-case in the application layer. It minimizes the sacrifice required to accept and redeem fast transfers/payments while providing more-than-ample security for microtransactions. This is supported on the premise that a Reddit user receiving points does need security yet generally doesn’t want nor need to wait for the same level of security as a nation-state settling an international trade debt. In any case, each Z-DAG transaction settles onchain at a block target of 60 seconds.

Syscoin Specs

Syscoin 3.0 White Paper
(4.0 white paper is pending. For improved scalability and less blockchain bloat, some features of v3 no longer exist in current v4: Specifically Marketplace Offers, Aliases, Escrow, Certificates, Pruning, Encrypted Messaging)
  • 16MB block bandwidth per minute assuming segwit witness carrying transactions, and transactions ~200 bytes on average
  • SHA256 merge mined with Bitcoin
  • UTXO asset layer, with base Syscoin layer sharing identical security policies as Bitcoin Core
  • Z-DAG on asset layer, bridge to Ethereum on asset layer
  • On-chain scaling with prospect of enabling enterprise grade reliable trustless payment processing with on/offchain hybrid solution
  • Focus only on Simple Value Transfers. MVP of blockchain consensus footprint is balances and ownership of them. Everything else can reduce data availability in exchange for scale (Ethereum 2.0 model). We leave that to other designs, we focus on transfers.
  • Future integrations of MAST/Taproot to get more complex value transfers without trading off trustlessness or decentralization.
  • Zero-knowledge Proofs are a cryptographic new frontier. We are dabbling here to generalize the concept of bridging and also verify the state of a chain efficiently. We also apply it in our Digital Identity projects at Blockchain Foundry (a publicly traded company which develops Syscoin softwares for clients). We are also looking to integrate privacy preserving payment channels for off-chain payments through zkSNARK hub & spoke design which does not suffer from the HTLC attack vectors evident on LN. Much of the issues plaguing Lightning Network can be resolved using a zkSNARK design whilst also providing the ability to do a multi-asset payment channel system. Currently we found a showstopper attack (American Call Option) on LN if we were to use multiple-assets. This would not exist in a system such as this.

Wallets

Web3 and mobile wallets are under active development by Blockchain Foundry Inc as WebAssembly applications and expected for release not long after mainnet deployment of Syscoin Core 4.2. Both of these will be multi-coin wallets that support Syscoin, SPTs, Ethereum, and ERC-20 tokens. The Web3 wallet will provide functionality similar to Metamask.
Syscoin Platform and tokens are already integrated with Blockbook. Custom hardware wallet support currently exists via ElectrumSys. First-class HW wallet integration through apps such as Ledger Live will exist after 4.2.
Current supported wallets
Syscoin Spark Desktop
Syscoin-Qt

Explorers

Mainnet: https://sys1.bcfn.ca (Blockbook)
Testnet: https://explorer-testnet.blockchainfoundry.co

Thank you for close consideration of our proposal. We look forward to feedback, and to working with the Reddit community to implement an ideal solution using Syscoin Platform!

Weekly Dev Update #19

THORChain Weekly Dev Update for Week 19–02 Nov 2019

Overview

1 Rune Fee

Reasoning about gas costs on networks with non-deterministic fee schedules (such as Bitcoin) becomes unnecessarily complex. The issue is that the final gas cost cannot be known ahead of time so the system must cover any variability in the gas cost so that the user can be charged a flat rate. If the user is not charged anything, then the system can be depleted of funds, passing the cost back to stakers. Additionally, swaps below 1 Rune bring negligible economic value to the network and saturate the mempool with low value transactions. As such the solution is to charge a flat 1 Rune fee (or 1 Rune equivalent) on all outgoing transactions (swap and withdrawals). This 1 Rune fee is moved into the Protocol Reserve and increases the network’s future income. When the nodes report on the final transaction, they include the observed transaction fee. This transaction fee is then reimbursed back to the pool that paid for it ( BNB.BNB, BTC.BTC, ETH.ETH etc). There are cases that the outgoing transaction fee may exceed 1 Rune (Bitcoin in high use), but more than likely 1 Rune will be more than sufficient to cover the costs and ensure the network grows its reserves. Additionally, it sets a floor on the minimum transaction that the network will process. A swap of less than 1 Rune will end up becoming a donation to the network.

THORChain Development

The team are working on 4 parallel streams of effort. Cross-chain infrastructure has now been merged into a single repo called “THORNode”. * THORChain * Midgard Public API * Threshold Signature Scheme implementation * Front-end Integration for BEPSwap

THORChain

Much work has been done to refactor and clean up the codebase which will make public audits easier. This includes splitting up the keeper, separating out the events module and more.

Weekly Dev Update #17

THORChain Weekly Dev Update for Week 12–18 Nov 2019

![](https://miro.medium.com/max/2880/1*Fy-NCZAKhgbZmE-iEIQChQ.png)

Recent Changes

Some recent updates to the protocol:

Update to Emission

The first iteration of the block reward scheme was announced in the previous weekly update. An immediate concern raised from the community was that the emission was too aggressive in the initial year and rewards dropped off fast beyond the 5 year mark. Taking Bitcoin’s emission as an example, the emission curve has been updated to target 2% emission after 10 years.
![](https://miro.medium.com/max/2384/1*gqBLvJOl2G4n3IHW1rViKg.png)
The Block Reward equation is given by the following recurrence equation: g(n+2) = ((R - (g(n+1) + g(n))) / x) / y Which evaluates to: ![](https://miro.medium.com/max/1624/1*ttpsRd7HUs2-7hvDGO6elg.png) where: R = Reserve, x = 6 (Arbitrary Emission Factor) y = (seconds per day / seconds per block) / days per year y = (86400 / 5) * 365.2425 The final curve thus has a Day 0 emission of 25%, Year 1 emission of 20% and Year 10 emission of 2%.

ChaosNet

The original plan for BEPSwap (prior to the Yggdrasil liquidity breakthrough) was to have it as a separate mainnet before launching the real THORChain in 2020 with cross-chain support. Now THORChain has in-built cross-chain support and a clear roadmap to 99 nodes. This means the mainnet launch will have public, community-run nodes at the start. The community has been fielding many questions about how to run a node, and the mechanics in doing so. Since the THORChain team will not be running any nodes, it is necessary to have a full-rehearsal with the community at launch. As such, the plan is for a public ChaosNet on 03 January 2020. ChaosNet will have the following key differences: * Minimum bond of 100k RUNE. * Maximum of 12 Nodes. * Churn cycle of 1 day. * Maximum stake amount of 600k RUNE total. * 2.7m RUNE Protocol Reserve to emit Bond and Stake rewards. * Hard-coded Ragnorök at 6 weeks.
Any member who wishes to join ChaosNet to get accustomed to running a node can do so, and will receive Block Rewards roughly equivalent to mainnet (25%). They will be setting up nodes, churning in, servicing the network and earning rewards. The system will hold up to 600k Rune, at which point it will refund any additional staked amount. The community can stake small amounts of real assets, prepare arbitrage bots, set up telegram alert bots and more. In short, it is a public rehearsal with the entire community across all facets (nodes, stakers, traders) so that everyone will have access to the same information and not unfairly benefit when the real mainnet launches. Additionally, the system will be hard-coded to perform a Ragnorök 6 weeks later, which will refund all the remaining reserve as well as bonded and staked assets. This will go a long way in re-assuring the community that the system can tolerate all levels of risk, including black-swan events, and that funds are safe at all times.

Internal Arbitrage

A new feature will be launched that will allow users to use internal arbitrage. This is an asymmetrical withdrawal to Rune, then immediately followed by a asymmetrical stake of Rune in another pool. A trader may want to do this instead of doing transactional arbitrage in order to exploit price differences between two pools the fastest way possible. Instead of an outgoing transaction being processed, followed by another incoming transaction, Rune balances and stakeUnits are swapped internally, being completed inside of a few seconds.

Fee-based Transaction Prioritisation

Currently there is no prioritisation to the order of transactions, all transactions are simply processed in order of time received. In moments of high demand of network resources (such as when there are large arbitrage opportunities and users are racing to exploit them), transactions will queue in the mempool. If the system cannot respond fast enough, then the reason for high demand will persist (the large arbitrage opportunity). The solution is to remove the reason for high demand in the first place, which is the large arbitrage opportunity, at the same time as collecting the maximum revenue for the system. As such, in the checkTx method (which can triage the mempool), transactions will be sorted and ordered in the value of the fee of the swap transaction. Assuming rational actors, the following transactions will then be prioritised over all others: * A transaction from an impatient swapper who is willing to pay a large fee. * A transaction from a trader who is able to arbitrage out a price discrepancy (and still make a gain).
This then means the system can collect as much income as possible (good for the stakers) at the same time as prioritising transactions that can arbitrage out large price discrepancies quickly. This then means swaps from transient swappers will experience a market price that accurately matches the reference price at all times.

BEPSwap Development

The team are working on 4 parallel streams of effort. Cross-chain infrastructure has now been merged into a single repo called “THORNode”. * THORChain * Midgard Public API * Threshold Signature Scheme implementation * Front-end Integration for BEPSwap

THORChain

Bug fixes, refactoring, as well as more logic around Yggdrasil funding. Additionally, node churn and the first part of block rewards PR was merged. * Add admin config event, fix tx out events https://gitlab.com/thorchain/bepswap/thornode/merge_requests/255 * Resolve “Select a satellite pool to swap out” https://gitlab.com/thorchain/bepswap/thornode/merge_requests/253 * Include the thorcli volume for the signer. https://gitlab.com/thorchain/bepswap/thornode/merge_requests/261 * Rune Reserves, block rewards, bond units, oh my! https://gitlab.com/thorchain/bepswap/thornode/merge_requests/258 * Add mechanism to slash a node account bond or rewards https://gitlab.com/thorchain/bepswap/thornode/merge_requests/264 * Add add event https://gitlab.com/thorchain/bepswap/thornode/merge_requests/262 * Issue198 node churn https://gitlab.com/thorchain/bepswap/thornode/merge_requests/270 * Issue199 — fix signer doesn’t process multiple txout item https://gitlab.com/thorchain/bepswap/thornode/merge_requests/271 * issue194: only rune get refund for invalid memo https://gitlab.com/thorchain/bepswap/thornode/merge_requests/272 * Outbound — mark txout item out hash based on the coin as well https://gitlab.com/thorchain/bepswap/thornode/merge_requests/273

Midgard Public API

Database ported from influxdb to timescaledb (more maturity, better developer tooling). Endpoints built out include/pools and /stakers. * Feature/new endpoint format, refactors and general clean ups
The OpenApi Schema can be reviewed here:
https://testnet-api.bepswap.net/v1/doc

Threshold Signature Scheme

TSS was successfully implemented into the Genesis ceremony, with the focus now being on the key-gen and key-sign ceremonies. Multi-cast DNS was switched out for a distributed hash table to facilitate node discovery. * Issue4 — docker images and ci https://gitlab.com/thorchain/tss/multi-party-ecdsa-dockemerge_requests/5 * Fix a docker bug https://gitlab.com/thorchain/tss/multi-party-ecdsa-dockemerge_requests/6
A proof-of-concept is being prepared using BinanceChain TSS library, which was recently launched in order to make a decision whether to switch libraries. A go-based implementation is better for THORNode, since it is also written in Go.
https://github.com/binance-chain/tss-lib

Frontend Implementation

Bug-fixes and tweaks from community feedback. The frontend is now ready for implementation with the latest Midgard API. * Resolve “Write cypress e2e test for pool stake list view” https://gitlab.com/thorchain/bepswap/bepswap-react-app/merge_requests/164 * Resolve “Update rune token icon” https://gitlab.com/thorchain/bepswap/bepswap-react-app/merge_requests/165 * Resolve “Update confirmation modal” https://gitlab.com/thorchain/bepswap/bepswap-react-app/merge_requests/166 * Resolve “Update wallet view” https://gitlab.com/thorchain/bepswap/bepswap-react-app/merge_requests/167 * Resolve “Add tooltip for wallet connection” https://gitlab.com/thorchain/bepswap/bepswap-react-app/merge_requests/168

Timelines

The team are working for these milestones: * Feature Freeze: 20 November 2019 on-time * Audit: 20 December 2019 on-time * ChaosNet: 03 January 2020 on-time

03-15 17:13 - 'The day the banks got a quantum computer.' (self.Bitcoin) by /u/Serialnvestor removed from /r/Bitcoin within 11-21min

'''
the day was like any other. I got up, got dressed, showered and then I went to work. I checked the btc price as I booted up my laptop and went to write a bit of angular code for an antiquated page that wouldn't work without angular.
I sighed. I went to check the btc balance... and wtf. That couldn't be right. There was simply no trading activity on bittrex. That was confusing. Bittrex was down, binance was not allowing logins, kucoin was saying that btc was "suspended" Well that was not good. I went to my old coinbase account, and tried to buy bitcoin. Coinbase wasn't selling. Gdax trading had stopped.
Well... shit. Time to look at the blockchain itself. I popped open block explorer, and I was horrified. There were millions of transactions that had all been triggered. The mempool was swamped. And every single transaction was sending the entire contents of their wallet to one of the btc eater addresses. The entire money supply of bitcoin had been... burned.
I sat back in horror. I searched the blockchain for my wallet. My measly hoard of 10.5 btc had also been burned. I now had... no money. This.... was bad.
I told my boss I was feeling ill, went to my bank, got my private key, booted up my bitcoin core wallet and looked at my balance. 0btc. This was... pretty terrible.
I turned on the television a month later. Apparently, wells fargo had bought a supercomputer from the nsa, because the nsa was broke, because their director had gotten into a fight with trump in 2021 over russian soldiers on us soil, and trump had gotten their funding reduced to zero dollars. So they had sold a quantum computer to wells fargo. Wells fargo had turned around and used that supercomputer to calculate the private keys of every bitcoin wallet in existence and then.... shut the network down. Burned it with fire. Boom. Gone.
They had gone through not just bitcoin but through thousands of alt coins.
There were only a few surviving cryptocurrencies that had survived the fiery attack by the banksters. Those were the quantum immune cryptocurrencies. They had changed their PoW algorithm, or they signed their addresses differently, or they used one time signatures.
There were congressional hearings, and several people went to jail, wells fargo disavowed use of a quantum device to destroy bitcoin but they were found out.
That was the day that bitcoin had a fork to bitcoin-q. It was a non contentious fork, but that was only the beginning of bitcoin's woes. People had lost faith in btc, and another crypto had risen to take its place in marketcap and individual coin price. It had been a small and insignificant alt before the quantum attack. It had been worth less than $5 before the quantum hack. Now, it was worth well over $5000 (in rubles). It had STOLEN btc's value.
And that all happened because on a forum post in 2018, 3 years before the btc hack went down, a lone cryptographer on the btc forums on reddit who was yelling at other redditors about the need for a quantum secure blockchain protocol had been ignored and the users had gone on without realizing the absolute horrifying quantum danger the good ship btc was sailing into...
We need to implement quantum secure wallets or some other method to prevent quantum attacks. This needs to have happened yesterday, because soon a quantum computer will emerge. And then a malicious person will get their hands on it. And they will use the quantum computer to steal bitcoin, burn the system down, or launch 51% attacks. Quantum is an emerging threat that can kill bitcoin in an instant if we don't fix the quantum loopholes in the blockchain's armor. So get off your thumbs, tweet to the devs, write proposals, write code and lets get to work implementing a patch of some sort.
